Persistent warm southerly flow and elevated dew points across the Northeast have limited nocturnal radiative cooling, keeping recent NYC minimum temperatures in the low-to-mid 70s and supporting trader focus on the 72–77 °F bins. National Weather Service guidance highlights partly cloudy skies and light winds that reduce heat loss after sunset, while model consensus shows only modest day-to-day variability tied to subtle shifts in low-level moisture and boundary-layer mixing. Official observations from LaGuardia and Central Park will resolve the market; small differences in cloud timing or dew-point depression could separate the tightly grouped leading outcomes. Historical June overnight lows average near 63 °F, underscoring the current positive anomaly.
